History Of Atomic Bombings On Hiroshima And Nagasaki
|
Invention of the atomic bomb was made use of in one of the most horrifying ways when it was dropped in Aug 1945 on the Japanese cities of Hiroshima and Nagasaki. A program code named the Manhattan Project got underway in mid-1942 to make the bomb. More than 100,000 personnel worked for 3 years before completing the invention of the first atomic bomb. On 16 Jul 1945, the bomb was tested in Trinity, New Mexico and the blast caused devastation equivalent to a bomb containing twenty kilotons of tri-nitro-toluene (TNT).

Hiroshima was targeted on 6th August 1945 and the bomb was dropped from B-29 plane called Enola Gay. It exploded almost 550m above the city releasing 15 tons of energy and intense heat. Around 130,000 to 200,000 people suffered injuries, died or disappeared. When the government in Japan tried to underplay the effect, the second bomb originally targeting Kokura was dropped on Nagasaki on 9th August. The local geography of Nagasaki averted excessive damage despite the release of twenty kilotons of chemical explosive. The explosion occurred over Urakami, which is north of the port.
The damage caused by the bomb resulted due to intense blast, thermal and nuclear radiation. The first 2 factors caused most of the damage and the effect was seen on people within a distance of one mile from the epicenter.
The military outcome of this bombing was acceptance of defeat by Japanese. The significance of atomic bombing was the large scale of catastrophe and death caused by dropping one bomb from one airplane.
